GEARlNG FOR WINDMILLS.

SPECIFICATION forming part of Letters Patent No. 633,619, datedSeptember 26, 1899.

Application filed June 17, 1899. Serial No. 720,945. (No model.)

To all whom it may concern:

Be it known that I, CHARLES E. SMITH, a citizen of the United States,residing at Napoleon, in the county of Henry and State of Ohio, haveinvented a new and useful Gearing for Windmills, of which the followingis a specification.

The invention relates to improvements in gearing for windmills.

The object of the present invention is to improve the construction ofwindmill-gearing and to provide a simple and comparatively inexpensiveone capable of affording great power or leverage on the upstroke of thepumprod and adapted to be readily adjusted to permit the length of thestroke of the pump-rod to be regulated.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a portion of awindmill provided with gearing constructed in accordance with thisinvention. Fig. 2 is a vertical sectional view of the same, taken atright angles to the windmill-shaft and showing the gearing in sideelevation. Fig. 3 is a horizontal sectional view on line 3 3 of Fig. 2,the gearing being shown in plan view. Fig. at is a detail viewillustrating the manner of hinging the vane.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

1 designates a frame or bracket forming a turn-table and provided with adepending tube 2, designed to be journaled in suitable bearings of awindmill-tower and receiving a reciprocating pump-rod 3, which ispivotally connected at its upper end to a walkingbeam or lever and whichis designed to be connected with a pump in the ordinary manner. Therotary frame or turn-table 1 is provided with a vertical portion 5,having bearings 6, 7, and '8 for a wind-wheel shaft 9 and forstub-shafts 10 and 11 of gear-wheels hereinafter described. Thehorizontal windwheel shaft 9 is preferably fixed in the bearings 6, andthe hub 12 of the wind-wheel rotates on the shaft and is located at oneside of the vertical portion of the rotary frame. Lugs 13 and 14 extendfrom the opposite side of the vertical portion of the rotary frame andare perforated for the reception of a vertical pintle 15, which hinges avane-casting 16 to the lugs. The vane, which is arranged at right anglesto the plane of the wind-wheel when the Windmill is in operation, swingsbetween the vertical portion of the rotary frame and an arm 17, whichextends from the lower portion thereof and which is adapted to form astop against which the vane abuts when it is arranged at right angles tothe plane of the wind-wheel. Any suitable means may be employed forholding the vane normally at right angles to the plane of thewind-wheel, and it is swung around to a position parallel with the planeof the wind-wheel by a suitable operating wire or rope 18 or otherfiexible connection secured to the vane and extending around pulleys 19and 20. The operating wire or rope extends downward through thedepending tube of the rotary frame, and the guide-pulleys 19 and 20 arehoused within suitable casings 21 and 22, mounted upon the rotary frame,on an extension or arm 23 thereof, and at a point adjacent to the upperend of the depending tube.

The hub of the wind-wheel has a pinion 24 fixed to it, and this pinionmeshes witha gearwheel 25, that is keyed or otherwise secured to thestub-shaft 10. The short shaft 10, which extends through the horizontalbearing 7, is provided at its rear end with a head 26, and thegear-wheel 25 is located at the other end of the short shaft 10. Theshaft 10 also carries an elliptical gear 28,which meshes with anelliptical gear 29 of the shaft 11, and the latter is mounted on therotary frame similar to the shaft 10, being provided at its outer endwith a suitable head 30. The elliptical gear 29 is provided with aradial series of perforations 31, adapted to permit aneccentrically-arranged wrist-pin 32 to be adjusted to vary the stroke ofthe pump-rod. The wrist-pin 32 pivots the lower end of a pitman 33 tothe outer elliptical gear 29, and the upper end of the pitman is pivotedto the adj acent end of the beam or lever at. The walking-beam or lever4, which is located above the gearing, is fulcrnmed at its center in asubstantially Lshaped bracket 34:, which is bolted or otherwise securedto the upper portion of the rotary frame and which is provided at itshorizontal arm with perforated ears to form bearings for the pivot ofthe beam or lever 4. As the gearing rotates the pumprod will bevertically reciprocated, and the elliptical gears are arranged to givegreat leverage on the upstroke of the pump-rod and to produce a quickreturn stroke, whereby a maximum power is obtained.

It Will be seen that the gearing for con necting the pump-rod with theWind-Wheel is eX- ceedingly simple and inexpensive in construction, thatit possesses strength and d urability, and that it enables the stroke ofthe pump-rod to be readily regulated. It will also be apparent that thegearing affords great leverage at the upstroke of the pump-rod, wherethe power is required, and that a quick return stroke is produced.

Changes in the form, proportion, size, and the minor details ofconstruction Within the scope of the appended claims may be resorted toWithout departing from the spirit or sacrificing any of the advantagesof this invention.

hat is claimed is 1. In a device of the class described, the combinationwith a frame, and a Wind-Wheel, of a walking-beam or lever fulcru medbetween its ends on the frame, a pump-rod connected with one end of thebeam or lever, elliptical gears meshing with each other, a pitmanconnecting one of the elliptical gears with the walking-beam or lever,and gearing connect ing the other elliptical gear with the wind- Wheel,substantially as described.

2. In a device of the class described, the combination of a rotaryframe, a wind-wheel, a walking-beam or lever fulcrumed on the frame, apump-rod connected with the Walking-beam or lever, elliptical gearsmeshing with each other, a p'itman eccentrically connected with one ofthe elliptical gears and extending therefrom to the Walking-beam orlever, the gear-Wheel 25, connected with the other elliptical gear, anda pinion meshing with the gear-Wheel 25, and connected with thewind-Wheel, substantially as described.

3. In a device of the class described, the combination of a rotary frameprovided with horizontal bearings 6, 7 and 8, a Wind-Wheel shaft.mounted in the bearing 6, short shafts extending through the bearings 7and 8 and provided at their outer ends with heads, elliptical gearsmounted on the short shafts, a gear-Wheel 25 fixed to the short shafts10, a pinion mounted on the Wind-wheel shaft and meshing with thegear-Wheel 25, a walkingbeam or lever fulcrumed on the frame andconnected with one of the elliptical gears, and a pump-rod connectedwith the Walking-beam or lever, substantially as described.

In testimony that 1 claim the foregoing as my own I have hereto aflixedmy signature in the presence of two Witnesses.
